You are probably missing the proper configuration directives, ex:

# /etc/sysconfig/network
NETWORKING_IPV6=yes
IPV6FORWARDING=no
IPV6_AUTOCONF=no
IPV6_AUTOTUNNEL=no
IPV6_DEFAULTGW=fe80::1               
IPV6_DEFAULTDEV=eth0

# /etc/sysconfig/network-scripts/ifcfg-eth0
IPV6INIT=yes
IPV6ADDR=2001:db8:xxxx:yyyy::zzzz/64     # replace with your static address
